Abstract
Accumulation of phytoecdysteroids in the agropopulations of R. carthamoides (Willd.) Iljin and S. coronata L., as well as their resistivity to phytophagans over the age periods of ontogenesis were investigated for 16 years. As a result of the investigations, the species-specific features of the accumulation of ecdysteroids in vegetative and reproductive organs of plants were determined; interrelations between the distribution of phytoecdysteroids in the structure of plants and the ecological relations with insects were revealed; the factors promoting damage were outlined; the damage caused by pests was evaluated.
